Parker 62CA-3 Compression Tube Union 3/16 in Brass

Product Description

The PARKER 62CA-3 is a brass compression tube union designed to join two lengths of tubing with matching compression-style end connections on both sides. It provides a leak-resistant, metal-to-metal seal without the need for thread sealant or flaring. Rated to 2800 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this union is built for demanding hydraulic, pneumatic, fuel, and instrumentation line applications. It is sized for 3/16 inch outside diameter tubing and is a standard stocking fitting for HVAC, refrigeration, and fluid power technicians.

This union fitting is used in residential and commercial applications wherever a straight, inline tube-to-tube connection is required. Common install scenarios include instrument tubing runs, fuel lines, hydraulic control circuits, and refrigeration pilot lines. The compression end connections allow field assembly without special tooling beyond a wrench, making it practical for service work in confined spaces or retrofit installations.

Key Features

• Compression x compression end connections on both sides for a tool-minimal, no-flare assembly
• Brass construction provides corrosion resistance and compatibility with a wide range of fluids and gases
• 2800 psi maximum working pressure suits high-demand hydraulic and pneumatic circuits
• Wide temperature range from -65 degrees F to 250 degrees F covers most field service conditions
• Accepts 3/16 inch OD tubing on both ends

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube union applications using 3/16 inch outside diameter tubing in fluid power, refrigeration, and instrumentation systems.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or fluid power mechanics depending on the system type. Before servicing any line, de-pressurize and isolate the circuit completely. Ensure tubing ends are cut square, deburred, and fully seated before tightening the compression nut to avoid leaks or ferrule damage. Follow applicable codes such as ASME B31.3 for process piping or manufacturer torque guidance where available.
